Determination Of Heavy Metal Concentration In Singed Cattle Skin (Ponmo) From Three Major Abattoirs In Umuahia Metropolis
ABSTRACT
Cowhides 'ponmo' flamed with tyre and firewood
were purchased from three abattoirs in Umuahia and Aba metropolis. Their heavy
metal contents of lead, cadmium, chromium, zinc, copper and Nickel were
determined before and after boiling. There was significant differences in the
levels of these metals with the exception of chromium and Nickel. The highest
levels of Cu (7.55mg.kg 1 ), Zn (13.76mg.kg 1 ) Fe (68.65mg.kg') were found in
hides processed with tyre while Cd (2.40mg.kg4) and Pb (0.7ling.kg ) content
were the highest in hides processed with firewood. However, the levels of
chromium and nickel were found to be the same in all the :rnples (0.olmg.kg').
The lowest levels of these heavy metals were usually found in hides processed
through the traditional method of boiling in water fbllowed by shaving. In Drximate
analysis, the samples had the compositions ranging from moisture (3.12-20.01%),
ash (0.11-4.17%), fat (0.21-0.62%), protein (6.06-8.68%), carbohydrate
(0.14.0.7l%) and crude fibre (34.43-40.15%). The result of sensory evaluation
of the different quality attributes based on the nine point hedonic scale
showed that sample 665 @onmo processed with firewood) was significantly higher
in all the sensoiy characteristics than sample 524 (ponmo processed with tyre)
and sample 482 (ponmo processed through the traditional method of boiling in
water followed by shaving).
